Projection television and mold for molding cabinet of the same

Abstract

A projection television (TV) and a mold for molding a cabinet of the same are capable of reducing the number of parts and simplifying a production process. The projection TV includes a cabinet that has an upper space holding a mirror and a lower space holding an optical unit, wherein the cabinet has a rear part supporting the mirror, a partition partitioning an inner space thereof into the upper space and the lower space, a front part closing a front of the lower space, and a base located at a bottom of the lower space, all of which are integrally molded.

1 . A projection television (TV) comprising:
 a cabinet comprising,
 a rear part, 
 a partition partitioning an inner space of the cabinet into an upper space and a lower space, 
 a front part closing a front of the lower space, and 
 a base located at a bottom of the lower space; 
   a mirror disposed in the upper space, wherein the rear part supports the mirror; and   an optical unit disposed in the lower space,   wherein the rear part, the partition, the front part, and the base of the cabinet are integrally molded.   
   
   
       2 . The projection TV as recited in  claim 1 , wherein the cabinet further comprises side parts configured to close opposite sides of the upper space, wherein the side parts are integrally molded with the rear part and the partition. 
   
   
       3 . The projection TV as recited in  claim 1 , wherein the partition comprises at least one opening configured to provide an optical path between the mirror and the optical unit. 
   
   
       4 . The projection TV as recited in  claim 1 , wherein the rear part is connected to a rear end of the partition and the front part is connected to a front end of the partition at an upper end thereof and a front end of the base at a lower end thereof. 
   
   
       5 . The projection TV as recited in  claim 1 , wherein the base comprises at least one rail configured to guide mounting of the optical unit. 
   
   
       6 . The projection TV as recited in  claim 3 , further comprising:
 a screen disposed on a front of the upper space;   a front panel coupled to a front of the cabinet and having an opening for exposing the screen; and   a rear panel coupled to the cabinet and configured to close a rear of the lower space.   
   
   
       7 . A projection television (TV) comprising:
 an integral cabinet having upper and lower spaces partitioned from each other;   a mirror disposed in the upper space of the cabinet;   a screen disposed on a front of the upper space;   an optical unit and at least one of electric and electronic parts disposed in the lower space;   a rear panel detachably coupled to a rear of the lower space; and   a supporting bracket mounted in the lower space, wherein the optical unit and the at least one of electric and electronic parts are mounted thereon.   
   
   
       8 . The projection TV as recited in  claim 7 , wherein the supporting bracket is slid and mounted in the lower space. 
   
   
       9 . The projection TV as recited in  claim 7 , wherein the cabinet comprises at least one guide rail configured to guide the mounting of the supporting bracket in the lower space. 
   
   
       10 . A mold for molding a cabinet of a projection television (TV), in which the projection TV comprises the cabinet having upper and lower spaces, a rear part at a rear of the upper space, a partition partitioning an inner space of the cabinet into the upper space and the lower space, a front part closing a front of the lower space, and a base at a bottom of the lower space, the mold comprising:
 first and second molds that are joined and separated in opposite directions, wherein the first and second molds define a mold cavity configured to form the partition, the front part, and an upper surface of the base; and   a third mold that is joined with the first and second molds in a direction perpendicular to the directions in which the first and second molds are joined, wherein the third mold defines another mold cavity configured to form a lower surface of the base.   
   
   
       11 . The mold for molding a cabinet of a projection TV as recited in  claim 10 , wherein:
 the first mold comprises a first molding part configured to form an inner surface of the upper space and a second molding part configured to form a front of the front part;   the second mold comprises a third molding part configured to form an outer surface of the rear part and a fourth molding part configured to form an inner surface of the lower space; and   the third mold comprises a fifth molding part configured to form the lower surface of the base.   
   
   
       12 . The mold for molding a cabinet of a projection TV as recited in  claim 11 , wherein the third mold comprises a plurality of ejector pins configured to separate the base from the third mold.
